5 INSTALLATION AND SET-UP.
5.1 Important remarks!
•
Loads at the secondary side must be connected at the SALIDA / OUTPUT side phase to phase.
(U2-V2 , V2-W2 , W2-U2 , see wire diagram)
•
To get the maximum effectiveness of the TSA filter the loads must be as balanced as possible
between the three possible pairs of phases (U2-V2 , V2-W2 , W2-U2 , see wire diagram)
•
Never connect a load between a phase and the PE (protection earth) cable.
•
Loads which do not produce 3
rd
harmonic, as incandescent lighting, heating, etc., do not need to
be connected to the TSA output. They can be connected at the primary side between phase and
neutral
•
The TSA must be connected to mains by the side named ENTRADA/INPUT. The three phases
shall be connected to U1, V1, W1and the neutral to N. The neutral is used only as auxiliary
supply for the protection elements. Do not connect it to the load side. (see fig.1)
•
Connect the PE terminal of the TSA to the protection earth cable in the existing installation.
•
Loads to be filtered must be connected to the side named SALIDA/OUTPUT. Terminals U2,
V2, W2 without the neutral (see wire diagram)
•
The 230 V output is phase to phase. All the single phase loads must be connected phase to
phase. If the TSA is mounted in an existing installation where loads were supplied between
phase and neutral , a new distribution has to be made, trying to keep the maximum balance
between the pairs of phases (U2-V2, V2-W2, W2-U2) , see wire diagram.
•
The earth cable to be distributed to the load is the already existing earth , connected to PE
•
Adjust the sensitivity and the desired delay for the earth leakage relay according to the load
needs and the desired selectivity. For TSA units with rated power below 50 kVA , adjust in the
